High School Biology Test
The spring 2012 high school Biology test was based on learning standards in the Biology content strand
of the Massachusetts Science and Technology/Engineering Curriculum Framework (2006). These learning
standards appear on pages 54 –58 of the Framework.
The Science and Technology/Engineering Curriculum Framework is available on the Department website
at www.doe.mass.edu/frameworks/current.html.
Biology test results are reported under the following five MCAS reporting categories:
■ Biochemistry and Cell Biology
■ Genetics
■ Anatomy and Physiology
■ Ecology
■ Evolution and Biodiversity
Test Sessions
The high school Biology test included two separate test sessions, which were administered on consecutive
days. Each session included multiple-choice and open-response questions.
Reference Materials and Tools
The high school Biology test was designed to be taken without the aid of a calculator. Students were
allowed to have calculators with them during testing, but calculators were not needed to answer questions.
The use of bilingual word-to-word dictionaries was allowed for current and former English language learner
students only, during both Biology test sessions. No other reference tools or materials were allowed.
Cross-Reference Information
The table at the conclusion of this chapter indicates each item’s reporting category and the framework
learning standard it assesses. The correct answers for multiple-choice questions are also displayed in the
table.

A species of newt produces a toxin
that can kill predators. Scientists have
observed that some garter snakes can
feed on the newts because they have a
natural resistance to the toxin.

from Pangaea was lost.
B. Organisms on the separated
continents no longer migrated
for breeding.
A. The garter snakes with resistance to
the toxin will successfully reproduce
and pass the trait on to their
offspring.
C. Ancestral organisms evolved into
different species on the separated
continents.
B. The garter snakes without resistance
to the toxin will acquire resistance
by increasing the rate at which they
feed on the newts.
D. Evolution in species proceeded more
slowly on the separate continents
than it had on Pangaea.
C. The newts that produce low levels of
toxin will also develop camouflage
adaptations that allow them to hide
from the garter snakes.
D. The newts will stop making the toxin
rather than continue to use energy
to make a toxin that is ineffective
against the garter snakes.

Read the information below and use it to answer the four multiple-choice questions and one
open-response question that follow.
ID:289978 Mod_5.eps Common EQ
One of the most important developments in modern medicine was the discovery of antibiotics. Antibiotics
are used to treat infections caused by bacteria. However, strains of bacteria that are resistant to antibiotics
are emerging. The rate of increase in infections caused by these antibiotic-resistant strains of bacteria is a
concern for human health.
The bacterium Streptococcus pneumoniae is a major cause of the respiratory disease pneumonia. The graph
below shows trends in bacterial resistance to different antibiotics in pneumonia cases from 1986 to 1999.
